| In this study chelating resins have been considered to be suitable materials for the recovery of Manganese(II) ions in water treatments. These modified resins were further reacted with 1,2-diaminoethan in the presence of ultrasonic irradiation for the preparation of a tridimensional chelating resin on the Nano scale for the recovery of Manganese II) ions from aqueous solutions. In this work we used copolymers derivate resin of poly (styrene – Alternative - Maleic Anhydride) and Atomic Absorption Spectroscopy for removing and determining Manganese(II) ions .The method is simple, sensitive, inexpensive and fast. The adsorption behavior of Manganese(II) ions were investigated by the synthesis of chelating resins at various pH’s. The prepared resins showed a good tendency for removing the selected metal ions from aqueous solution, even at acidic pH. Also, the prepared resins were examined for the removal of Manganese(II) ions from real samples such as industrial wastewater and were shown to be very efficient at adsorption in the cases of Manganese(II) ions . The pseudo-first-order, pseudo-second-order and intra-particle diffusion kinetics equations were used for modeling of adsorption data and it was shown that pseudo-second-order kinetic equation could best describe the adsorption kinetics. The intra-particle diffusion study revealed that external diffusion might be involved in this case. The resins were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction analysis. | ||

| چکیده [English] | ||
| در این مطالعه رزینهای کیلیتی بهعنوان مواد مناسبی برای بازیابی منگنز (II) از محلولهای آبی مورد ارزیابی قرار گرفت. این رزینهای اصلاح شده در حضور اشعه ماواربنفش با 1و2-دی آمینو اتان واکنش داد تا یک رزین سه بعدی در مقیاس نانو حاصل شود. رزین مورد استفاده در این کار کوپلیمری از پلی استایرن/مالئیک انیدرید بود که با روش جذب اتمی حذف یونهای منگنز از محلول آبی مورد مطالعه قرار گرفت. روش ساده، حساس، ارزان و سریع میباشد. رفتار جذبی رزین در pHهای مختلف ارزیابی شد که نشان داد حتی در pH های اسیدی نیز حذف یونهای انتخاب شده انجام میشود. رزین مورد اشاره جهت حذف منگنز از نمونههای حقیقی نظیر آب فاضلابهای صنعتی بهکار رفت که نتایج خوبی از حیث کارایی حاصل شد. معادلات سینتیکی نفوذ درونذرهای، شبه مرتبه دوم و شبه مرتبه اول برای شبیهسازی دادههای جذبی بهکار رفت و نشان داد، دادهها با رفتار سینتیکی شبه مرتبه دوم مطابقت دارد. مشخصهیابی رزین با روشهای FT-IR، SEM و XRD انجام شد. | ||
